Google Fiber vs Quantum Fiber: Which Should You Get?

Short answer: Whichever one actually serves your address

Google Fiber and Quantum Fiber are both fiber to the home, so neither has a structural advantage in how the connection behaves. The differences that remain are plan tiers, contract terms and customer service — real, but secondary. In most neighborhoods only one of the two has built, which settles it before preference does.

Google Fiber is fiber to the home, operated by Google LLC. Quantum Fiber is fiber to the home, operated by Lumen Technologies, Inc..
Google Fiber: plans commonly range from 1 Gbps up to 8 Gbps where available.
Quantum Fiber: plans commonly range from 500 Mbps up to 8 Gbps where available.
Both operate in 3 of the markets FiberNear tracks, so this is a real choice rather than a hypothetical one in those cities.
Both are built out address by address. Whichever reaches your specific property usually settles the question before preference does — FiberNear checks that free.

Where Google Fiber and Quantum Fiber overlap

These are the markets FiberNear tracks where both networks operate, so the comparison is a real decision rather than a hypothetical. The percentage is the share of each city's residential locations reached by fiber of any brand, from FCC filings — it describes the market, not either company's own footprint.

Markets where both providers operate
Market	Fiber available	Cable available
Denver, CO	64.2%	93.3%
Phoenix, AZ	27.1%	73.7%
Salt Lake City, UT	79.6%	97.5%

How often each one is actually available

Specifications decide which connection is better. Availability decides which one you can buy, and it is the part comparison pages usually skip. Across the 29 markets FiberNear holds FCC data for, this is how much of each city the two technologies reach at 100/20 Mbps or better:

Google Fiber is fiber, and fiber reaches a median of 64.2% of locations in a typical tracked market.
Quantum Fiber is fiber, and fiber reaches a median of 64.2%.
Both run on the same kind of network, so availability does not separate them at the market level. It separates them street by street, which is the only level that matters here.

Source: FCC Broadband Data Collection, residential fixed broadband, as of December 31, 2025. Figures are advertised availability self-reported by providers, not measured speeds. These are technology-level figures, not brand-level ones — the FCC's public summary files report how much fiber or cable reaches a city, but not which brand owns it, so no coverage percentage here should be read as a figure for Google Fiber or Quantum Fiber specifically.

Common questions

Which is better, Google Fiber or Quantum Fiber?

Is Google Fiber faster than Quantum Fiber?

On advertised download speed the two are closer than most people expect. The difference that matters is upload: Google Fiber is fiber to the home and Quantum Fiber is fiber to the home, and those two technologies behave differently on upload and latency even when the download figure looks similar. Advertised tiers are set by each provider and vary by address.

Can I get both Google Fiber and Quantum Fiber at my address?

Sometimes, but far less often than the coverage maps suggest. Both networks are built out street by street, and plenty of addresses that show inside both footprints can only actually order one. Entering your address is the only way to find out which — FiberNear checks it free and there is no obligation.

Is FiberNear paid to recommend one of these?

No. FiberNear is an independent comparison and referral service, not an internet provider, and it is not affiliated with, endorsed by, or sponsored by any carrier named here. We may be compensated if you choose to move forward with a provider, which never changes which options we show you.
